Hi there,
I have a cluster of problems that have occurred simultaneously on my Asus Zenbook laptop running Windows 11. The issues are as follows:
The inbuilt speakers have stopped working. Sound will still play through hardwired or bluetooth speakers or headphones.
The media keys (controlling e.g. volume, brightness etc.) will no longer 'lock'. I previously had it set that I held 'fn' to use the regular function keys (f1-f12), but that without fn held the relevant keys would control brightness etc. Now it has revered to having to hold 'fn' to do the latter. You can supposedly cycle between these options by pressing fn+esc. When I try this I get an onscreen indication that the function is switching, but nothing changes.
My touchscreen, which I had previously disabled, has re-enabled itself.
Periodically, the light on the 'camera' function button (one of the fn buttons) will come on to indicate that the camera is switched off, pressing this button will (after a massive lag) cause the 'camera is off' indicator to appear onscreen but will never turn it on. Restarting the PC resolves this (but none of issues 1-3).
Any suggestions as to what might be going on here. My first guess is that maybe a windows update caused some kind of conflict with the mainboard firmware?
